Psyllium is native to Iran and India and is currently cultivated in these countries. The seeds are primarily used in traditional herbal medicine. Psyllium seed husks are mainly used to treat constipation.
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

In addition to its traditional and current use for constipation, psyllium was also used topically by herbalists to treat skin irritations, including poison ivy reactions and insect bites and stings. It has also been used in traditional herbal systems of China and India to treat diarrhea, hemorrhoids, bladder problems, and high blood pressure.
Psyllium is a bulk-forming laxative and is high in both fiber and mucilage. Psyllium seeds contain 10–30% mucilage. The laxative properties of psyllium are due to the swelling of the husk when it comes in contact with water. This forms a gelatinous mass that keeps feces hydrated and soft, provided it is taken with sufficient water. The resulting bulk stimulates a reflex contraction of the walls of the bowel, followed by emptying.
Psyllium is a common ingredient in over-the-counter bulk laxative products. One preliminary trial found that psyllium seeds relieved constipation when it was due to lifestyle factors (e.g., inadequate fiber, sedentary lifestyle), but not when an actual disease was the cause. Numerous double-blind trials have found that supplementation with psyllium can lower total cholesterol and LDL (“bad”) cholesterol. However, levels of HDL (“good”) cholesterol are not affected by psyllium supplementation. The cholesterol-lowering effect of psyllium has been reported in children, as well as in adults. Psyllium supplementation has also improved blood sugar levels in some people with diabetes. The soluble fiber component of psyllium is believed to account for this effect.
In a double-blind trial, people with ulcerative colitis had a reduction in symptoms such as bleeding and remained in remission longer when they took 20 grams of ground psyllium seeds twice daily with water compared to the use of the medication mesalamine alone. Also, the combination of the two was slightly more effective than either alone.
The suggested intake of psyllium husks to treat constipation is 1 teaspoon (approximately 5 grams) three times per day. Alternatively, some references suggest taking 2–6 teaspoons (10–30 grams) of the whole seeds per day—typically taken in three even amounts throughout the day. This is stirred into a large glass of water or juice and drunk immediately before it thickens. It is best to follow label instructions on over-the-counter psyllium products for constipation. It is important to maintain a high water intake when using psyllium.
